Set cookiecutter vesrion to 1.3.0
Set cookiecutter vesrion to 1.3.0

The latest cookiecutter version (1.4.0) has issues with
poyo dependency for parsing yaml files which are started
from '---' (more info: https://github.com/hackebrot/poyo/issues/3).
To prevent CI falures we need to hard-code cookiecutter version
to 1.3.0. Once poyo issue is resolved we can use latest cookiecutter.
